(list boxes are particularly conspicuously absent), it has no event handling at all, and it isn't in any way integrated into pterm - you have to build it specially using the test stubs in gtkdlg.c. But what there is so far seems to work plausibly well, so it's a start. Rather than browbeat the existing GTK container/layout widgets into doing what I wanted, I decided to implement two subclasses of GtkContainer myself, which implement precisely the layout model assumed by the config box specification; this has the rather cool consequence that the box can be resized and will maintain the same layout at all times that it would have had if initially created at that size. [originally from svn r2931]
